{"id":"CVE-2025-39832","summary":"net/mlx5: Fix lockdep assertion on sync reset unload event","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5: Fix lockdep assertion on sync reset unload event\n\nFix lockdep assertion triggered during sync reset unload event. When the\nsync reset flow is initiated using the devlink reload fw_activate\noption, the PF already holds the devlink lock while handling unload\nevent. In this case, delegate sync reset unload event handling back to\nthe devlink callback process to avoid double-locking and resolve the\nlockdep warning.\n\nKernel log:\nWARNING: CPU: 9 PID: 1578 at devl_assert_locked+0x31/0x40\n[...]\nCall Trace:\n\u003cTASK\u003e\n mlx5_unload_one_devl_locked+0x2c/0xc0 [mlx5_core]\n mlx5_sync_reset_unload_event+0xaf/0x2f0 [mlx5_core]\n process_one_work+0x222/0x640\n worker_thread+0x199/0x350\n kthread+0x10b/0x230\n ? __pfx_worker_thread+0x10/0x10\n ? __pfx_kthread+0x10/0x10\n ret_from_fork+0x8e/0x100\n ? __pfx_kthread+0x10/0x10\n ret_from_fork_asm+0x1a/0x30\n\u003c/TASK\u003e","modified":"2026-05-18T05:57:29.319557899Z","published":"2025-09-16T13:08:49.513Z","related":["SUSE-SU-2025:03600-1","SUSE-SU-2025:03634-1","SUSE-SU-2025:20851-1","SUSE-SU-2025:20861-1","SUSE-SU-2025:20870-1","SUSE-SU-2025:20898-1","SUSE-SU-2025:21074-1","SUSE-SU-2025:21139-1","SUSE-SU-2025:21179-1","SUSE-SU-2025:3751-1","SUSE-SU-2025:4057-1","SUSE-SU-2025:4132-1","SUSE-SU-2025:4141-1","openSUSE-SU-2025:20081-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/39xxx/CVE-2025-39832.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/06d897148e79638651800d851a69547b56b4be2e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0c87dba9ccd3801d3b503f0b4fd41be343af4f06"},{"type":"WEB","url":"https://git.kernel.org/stable/c/902a8bc23a24882200f57cadc270e15a2cfaf2bb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ddac9d0fe2493dd550cbfc75eeaf31e9b6dac959"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/39xxx/CVE-2025-39832.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-39832"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"7a9770f1bfeaeddf5afabd3244e2c4c4966be37d"},{"fixed":"ddac9d0fe2493dd550cbfc75eeaf31e9b6dac959"},{"fixed":"0c87dba9ccd3801d3b503f0b4fd41be343af4f06"},{"fixed":"06d897148e79638651800d851a69547b56b4be2e"},{"fixed":"902a8bc23a24882200f57cadc270e15a2cfaf2bb"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-39832.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.5.0"},{"fixed":"6.6.104"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.45"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.16.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-39832.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
